Hello Ramyasri,

TS EAMCET rank will be given based on your TS EAMCET exam marks and your PCM aggregate* in your 10+2 or any qualifying examination.

So these two marks constitute the total score which contains 75% of TS Eamcet marks+25% of PCM aggregate.

*PCM aggregate is the average marks of the marks obtained in only Maths,physics,chemistry in your Intermediate.

Your TS Eamcet online test marks alone don't determine your rank, your PCM marks are required to know your rank.

Anyways go through the analysis below to get an idea of your rank
